IMPRO VEMENT IN SPRING AND DUSTER FOR WATCHES.

Specification forming part of Letters Patent No. 80,989, dated August 11, 1868.

To all whom it may concern:

Be it known that I, J OHN H. MoRsE, of Peoria, and county of Peoriaand State of Illinois, have invented a new and useful Improvement in Lift-Spring and Duster Combined for Watch-Gases; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanyin g drawings, and to the letters of reference marked thereon.

Figure 1 shows watch-case with lift-spring and duster in position; Fig. 2,1ift-spring and duster Fig. 3,lift-spring;- Fig. 4, lift-spring, ease, and duster; Fig. 5, working plan.

My improvement consists in fitting a steel spring of proper shape (see Fig. 3) in a metal case, (see Fig. 4,) and adjusting this case to a hunting-case watch. (See Fig. 1.)

Using the spring (Fig. 3) F as a lift-sprin g, and the metal case (Fig. 4) D for a duster, the lift-sprin g raises the lid of the watch by means of the tongue A of spring passing up through slot B from-the inside of the watch-ease and pressing on the lid 0, as seen in Fig. 1 and working plan, Fig. 5, the metal easeD so fitting the watch-case as to prevent the dust entering at the hole B, Fig. 1, and comin gin contact with the movement of the watch. These metal cases I), Fig. 4, may be made at the factory when the watch-cases are made, and each watch-case has its own case and duster D, Fig. 2, or may be made at any time for any watch-ease. They should be so constructed that every spring F will fit every ease D, near the same size, as in this I claim an improvement over the old lift-spring. Should the spring F break, the ease D may be removed from the watchcase by ta-kin g out the screws E E, (see Fig. 1,) replacing the broken spring by a new one, and returning the whole to the watch-ease. By this arrangement there is no fitting of springs, drilling new holes, or cuttin g away of watch-ease, for each watch-case will have its own case and dusterD, and springs can always be had ready fitted to them.

Claim.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

The metal case D, with its steel spring F, to be used as a liftsprin g and duster for watchcases, in the manner and for the PLLIPOSG specilied.
